A kind of breeding method of Nubian goat

Abstract

The invention relates to the technical field of goat breeding, in particular to a Nubia goat breeding method. The raising management and the pasture management are combined; male goats and female goats are subjected to nutrition regulation and control in different periods; aphrodisiac mating is used as assistance; the concrete processes are shown as follows: in three months before the mating, the male and female goats are fed in different houses; the pasture time every day is not less than 4h; in 1 month before the pasture, the male and female goats are fed in a mixed way; the daily ration quantity is increased; in one week before the mating, on the basis of the former management, premixed materials are fed in a supplementary way; in the mating period, the pasture time of the breeding goats is not less than 5h per day; aphrodisiac feed is fed for the male and female goats; milk, eggs, mixed concentrated feed and coarse fodder are matched for feeding; the female goats in the gestational period are fed in a quantity increasing way; in addition, the pasture time every day does not exceed 3h. The method provided by the invention has the advantages that the health growth and the nutrition requirements of the goats can be maintained; the fertilization success ratio and the lambing percentage can be improved; the goat breeding performance is further enhanced.

Description

technical field [0001] The invention relates to the technical field of goat reproduction, in particular to a breeding method for Nubian goats. Background technique [0002] The Nubian goat is a subtropical species with a tall body, high meat production rate and strong adaptability. After several years of hard work in my country, it has been successfully bred to adapt to the climate of our country, and has shown good growth of the Nubian goat. Ability, under the background of the modern sheep breeding industry pursuing early maturity, multiple births, fast growth and development, and high meat quality, the initial mating time for Nubian rams is 6-9 months, and the mating time for ewes is 5-7 months , the estrus cycle is 20 days, and the estrus duration is 1-2 days. Its reproductive effect can no longer meet the needs of the modern sheep industry. [0003] Reproduction and growth are the two main economic traits of breeding output. Among them, the reproductive benefits of ewes ...

Problems solved by technology

[0004] For example, the patent number is 201510335810.7, "The Breeding Method of Goats" discloses the method of rational mating by using the technology of semen test and emotion test. This method has a high fertilization rate, but its cost is high and the technical requirements are high

[0005] The cost of artificial insemination is high and the technical requirements are high. Most farmers in my country cannot achieve artificial insemination. Therefore, most farmers usually use aphrodisiac methods to adjust the estrous cycle of goats and conduct mating in a controlled manner. However, the factors that affect the reproductive capacity of goats are not single. Among them, factors such as nutrition, climate, age, season, and breeding technology may all have an impact, and in the existing aphrodisiac methods, drugs and hormones are mainly used to aphrodisiac, which can increase the conception rate, but it is prone to deformities, and Reduced drug resistance in ewes

[0006] For example, the patent No. is 201210412394.2, and "A Feed for Improving Goat Reproductive Ability" discloses the use of snails, salt, earthworms, calamine, sand garden seeds, cypress kernels, Schisandra chinensis, Ligustrum lucidum, kelp, fleece-flower root, astragalus, curculiculatus, Poria cocos, cinnamon, Eucommia ulmoides, Morinda officinalis, Atractylodes macrocephala, heterophylla, and silkworm excrement are used as raw materials to make feed, which improves the libido and semen quality of breeding goats, but the cost of raw materials is relatively high
